(54) AN ENGINE COOLING SYSTEM HAVING A LOW SPEED COOLING PACKAGE FAN


(57) A machine engine enclosure arrangement that has sound reducing elements allows for the overall sound rating of the machine to be decreased. The engine enclosure includes a housing that has a housing length and a housing width. The housing defines a housing axis that extends along the housing length and the housing axis defines a vertical reference plane. The vertical reference plane is perpendicular to a ground surface on which machine is resting. The engine enclosure further includes a radiator fan that is configured to provide air flow across the radiator. The radiator fan has a diameter greater than the housing width and defines a fan plane perpendicular to an axis of rotation of the radiator fan. The radiator fan is positioned between the side walls of the housing so that the fan plane is at a non-perpendicular angle with respect to the vertical reference plane.
